Shuttle



y 31, 1932- J.IB. DAUDELIN 5 SHUTTLE Filed Aug. 15. 1929 Janmudelin Patented May 31, 1932 UNITED STATES PATENT OFFICE Application filed August 13, 1929. Serial No. 385,617.

My present shuttle is an improvement upon earlier loom shuttles of the automatically threading type heretofore patented by me, particularly in respect to the threading feature, and aims to provide that certainty and positiveness of threading action regardless of the direction of travel of the shuttle at the moment of threading, so necessary in a shuttle of this type. V

Another feature consists in the design and structureof the shuttle itself to the end that the thread will be positively controlled, tensioned, and guided during the run of the shuttle, all in a construction requiring such slight change of existing shuttle structure as to be capable of embodiment therein at the minimum cost.

These and various other features of utility and advantage are secured in the shuttle forming the subject matter of my present invention, the construction and operation of which is described and illustratedin the accompanying specification and drawings. In the drawings:

Fig. 1 is a fragmentary plan view at the threading end of a shuttle of standard type equipped in accordance with my invention and showing the shuttle threaded. a

.Fig. 2 is a side view thereof.

Fig. 3 is a view similar to Fig. 1, partially in horizontal plan section.

Fig. 4 is a cross section on the line 4-4, of Fig. 3 and Fig. 5 is a view similar to Fig. 1, but showing a'slight modification, and a Fig. 6 shows a further modification in which the anchoring end of-the pin serves as a snubbing post. I a I V The shuttles shown are of standard manu- 40 facture and includea body 1 formed to provide a bobbin chamber 2 in which ismounted a bobbin 3'having a filling 4; wound thereon.

Forwardly of the bobbin chamber, the shuttle body extends. as a threading end, indicated generally at 5, having the usual threading slot which consists of a longitu dinal slot portion 6 in-its top wall connecting adjacent the tip of the shuttle with the downwardly' and rearwardly extending slot portion7 in the side wall of the shuttle, said rearwardly extending slot portion opening into the shuttle eye 8, which is a simple bore extending transversely across the shuttle at substantially the rear end of the'longitudinal slot 6 and beneath the same. I In threading, the filling 3 from the bobbin is laid from above in said longitudinal slot 6, as indicated in dotted lines Fig. l, and is drawn through said rearwardly extending slot 7 until it is lodged in said eye 8, after which the filling runs directly from the bobbin through the eye. r In order properly to guide and direct the filling both during the threading action and subsequently int-he run of the shuttle, I place adjacent the threading slot and in the eye certain instrumentalities which so combine and cooperate with each other as to secure this result, regardless of the direction of travel of the shuttle at the moment that the threading action occurs. f

In accordance with my present invention I lodge in the body of the shuttle adjacent the threading slot a combination thread guide and deflector member 9. This may consist 76' of a simple pin or length of bendable wire, which in the form of my invention shown in Figs. 1 to 4 inclusive is driven as a straight pin'from front to rear through the overhanging nosing portion 10 of the shuttle defined 80 by the slots 6 and 7 and eye 8 and is then bent at substantially right angles upon itself to provide at its rear end a downwardly extending substantially verticallydisposed an choring portion 11.

The forward end 12 of the pin 9 is exposed beyond the nosing portion 10 of the shuttle as a thread deflective portion disposed at substantially the juncture of the slots 6 and '7 and past which the thread is adaptedto be drawn in threading the shuttle.

This exposed portion 12 of the pin or wire is preferably arranged diagonally with respectto the longitudinal slot 6, but since the material of the pin is bendable, may be bent to any desired angle. If desired, the Wall of said slot opposite theterminus of said pin or wire 9 may be undercut slightly as indicated at 13 to insure proper clearance of the thread.

wire is to deflect the thread in the threading H action of the shuttle from the slot 6 into the slot 7, as well as to prevent improper escape of the thread after the shuttle has been threaded, by ballooning or the like. In the performance of its deflecting function, the I position of the deflective portion 12 at the forward end of the slot 6 and in substantially the longitudinalaxis of the shuttle is well adapted to accomplish this result, since the tip of the shuttle is the logical point .atwhich to turn the thread from the slot 6 into the slot 7 and in the performance of itssecond function, such position brings the portion 12 over the forward end of the slot 7 as an overlying barrier past which the thread cannot escape by a direct upward lifting action.

Cooperating with the member 9 is the eyepiece proper of the shuttle. This eye piece is a simple coil or turn 1 1 of wire or the like lining the outer end of the shuttle eye 8'. It is preferably made in one piece to provide an anchoring-portion 15 which is driven into the side wall of the shuttle above the rear end of the slot 7 and forwardly of the eye 8, the fore end of the turn or coil 14 extending transversely across the shuttle above the eye as a shank 15 which not only assists to fix the eyepiece in position in the eye, but also serves as a barrier to prevent improper escape of the thread from the eye, after the shuttle has been threaded, by' an upward lifting .movement which might cause :the thread to lift into the vertical threading slot 6. 1 After the shuttle has been-threaded the filling runs directly from the bobbin into the eye, being turned thereinto by a snubbing post 16 which is driven vertically intothe shuttle from below. If desired, the eye; may be filled with yarn or the like, as indicated at 17, to tension the thread'passi-ng therethrough, Q

It will be noted that in addition to its guiding and barrier functions, the pin or wire introduces a factor of strength into the nosing 10.

As illustrated in Fig. 6 instead of driving a separate pin to form the snubbing post 16, the downturned end 11 of the-wire 9 may be so deflected as to occupy the position ordinarily occupied bythe separate and inde. pendent post 16 in. which event such end 11 would act as the snubbing post as-well as the anchorage for the wire. In such event the combination snubbing post and anchoring pin portion 11 of the guide member 9 is first bent downwardly at substantially right angles to the guide member, and such member is thereafter driven into the wood of the shuttle from above. \Vhcn so driven said member is embedded in the upper surface of the shuttle nose.

Various other modifications in the design and oonstructionof my device may obviously be resorted to, all wlthont departing from the spirit of my invention if within the limits" of the appended claims.
